Question

Manufacture of ammonia by Haber's process involves the reaction N 2+3 H 2 leftharpoons 2 NH 3 ; Δ H =-22.4 kcals. The effect of increase of temperature on the equilibrium is (A) Equilibrium is shifted to the right (B) Equilibrium is unaffected (C) Equilibrium is shifted to the left (D) Equilibrium is shifted first to right then to left

Tardigrade Admin · Accepted Answer

Formation of NH 3 is exothermic. When the temperature is increased, the reaction will proceed in the backward direction so as to absorb heat and nullify the effect of increasing temperature. In other words, the equilibrium will shift to left

Q. Manufacture of ammonia by Haber's process involves the reaction $N_{2} + 3 H_{2} ⇌ 2 N H_{3}; Δ H = - 22.4$ kcals. The effect of increase of temperature on the equilibrium is

Equilibrium is shifted to the right

Equilibrium is unaffected

Equilibrium is shifted to the left

Equilibrium is shifted first to right then to left

Formation of $N H_{3}$ is exothermic. When the temperature is increased, the reaction will proceed in the backward direction so as to absorb heat and nullify the effect of increasing temperature. In other words, the equilibrium will shift to left
